For the past month I've been mostly working on improving the kernel code in the ptrace(2) API. Additionally, I've prepared support for reading NetBSD/aarch64 core(5) files. A critical Problem Report kern/51630 regarding lack of PTRACE_VFORK implementation has been fixed. This means that there are no other unimplemented API calls, but there are still bugs in the existing ones. With fixes and addition of new test cases, as of today we are passing 961 ptrace(2) tests and skipping 1 (out of 1018 total). Plan for the next milestone Cover the remaining forking corner-cases in the context of debuggers with new ATF tests and fix the remaining bugs. The first step is to implement proper support for handling PT_TRACE_ME-traced scenarios from a vfork(2)ed child. Next I plan to keep covering the corner cases of the forking code and finish this by removal of subtle bugs that are still left in the code since the SMP'ification. http://blog.netbsd.org/tnf/entry/forking_fixes_in_the_context This work was sponsored by The NetBSD Foundation.
